- (Villars, 1991) corrects (Hund, 1949), changing the positions of one third of the fluorine atoms so that the space group becomes $Fm\overline{3}m$ #225, as is accepted for $D0_{3}$, and in agreement with (Hassel, 1929). This structure is crystallographically equivalent to the Heusler ($L2_{1}$) structure and a derivative of the
quaternary-Heusler,
LiMgAuSn.
